There are two parts of the setup of an "external
soundcard" interface like the SignaLink: the computer
side and the radio side. (Sorry if that was a "doh!")
As others have pointed out, the radio side is pretty
easy--you use a cable specific to your radio, and then
adjust the signal level to the radio using the Tx knob
on the SignaLink.
The computer side has a few more steps, but it's
still pretty easy. It's a single USB cable, so the
mechanical part is easy. Once you plug it in (and both
the computer and SignaLink are powered on), the computer
should recognize the external sound card and then set it
up. You then have to make sure that the external sound
card is selected for your PSK program and nothing else.
You can continue to use the computer's sound card for
other audio functions, like sound on web sites, Windows
sounds, etc. But don't let Windows use the SignaLink's
sound card for any of those functions or you risk
transmitting things like Windows chimes and music over
the air. Somewhere in your PSK program should be a menu
to select the SignaLink. (Note that it might not
actually be called "SignaLink" to Windows--it might have
a name based on the chipset inside. Before you plug it
in, take a note of what your internal sound card is
called, and then look for the new one after the
SignaLink is plugged in.) Finally, set the gain of the
audio going to the PC using the Rx knob on the
The last thing to do is configure the virtual COM
port used for PTT. Rather than try to figure it out
logically, I just tried the various choices in the PSK
program until I found the one that keyed the radio.
I used a SignaLink USB at the "rental" station in
Guam, so it's been a while since I've used one, but one
thing I do remember is try not to use different USB
ports on the computer if you have to disconnect and then
reconnect the SignaLink. IIRC, if I used the same port
then the computer and software remembered the settings.
If I used a different USB port, then I had to change the
settings in the software (like the number of the virtual

I've do a little bit mor digging and found an
"external soundcard" might
work bu-t I don't know how easy it is to configure.
Let me also explain I
don;t have the hand control to do ANY assembly on my
own so and
suggestions of "kits" or home made interfaces is our.
I also did the same
